Why does a pencil sharpener break the lead after using it a few times and then sharpening the pencil

That's right, generally speaking, an ordinary pencil sharpener is fine, like sunwood (sunwood) is a very ordinary brand, I have used it, ten dollars, you can do it. No need to buy such expensive ones.

It is generally a problem with the design of the pencil sharpener, or it can be said that it is a problem with your use.

Hold the pencil sharpener in your left hand, hold the crank handle in your right hand, plug the hole of the pencil, vertically towards the ground, and turn the crank handle with your right hand ten times, one turn each time, the purpose is to make the pencil sawdust in the gear disc of the cutter head be cleaned out and keep the gear disc clean. Then you remove the plastic box containing the sawdust and take a look for yourself, and the wood chips in the general gear disc have been cleaned up. At this time, if you roll the pen again, the core will not be broken.

The pencil sharpener used at the beginning will not be like this, after using it for a period of time, there will be a problem of broken core, so you can use the above posture and direction every time you roll the pencil, and the sawdust of the pencil will not fall into the gear disc, and it will not lead to the next broken core of the pencil.

Before rolling the pen, you can remove the plastic box, pour out the sawdust, by the way to see if there is any sawdust in the gear disc, if there are sawdust, the pen is easy to break the core, clean it up according to the above method, when the pen is rolled again, the pencil refill will not break.

This problem can be said to be a design problem, but also a problem of use, the above is my practical experience with a pencil sharpener for many years, I hope it can be helpful to everyone.

Thank you. Remember to reply.

One is that your pencil sharpener is no longer sharp. The second is that the quality of your pencil is not good, and the third is that the pencil foam in your knife is not cleaned. Also, your knife is broken.

The pencil sharpener has been used for a long time: a knife is dull, and there is a part of the plastic that wears out, making the gap larger, and the lead is easy to break. It would be nice to get a new one.

You can buy a little better, just 20 pieces, and the clamping part is better with metal teeth. It is estimated that it will take half a year to a year to change one. Otherwise, the broken pencil is enough to buy a new pencil sharpener, and it is particularly time-consuming, which is depressing!

Sometimes a pencil is put in it, and only half of it is ......... when it is sharpened

Because there is a problem with the pen, it may have been broken.

The pencil sharpener may not sharpen the pencil because the refill is broken, which can generally be seen against the light, if the light is not transparent, it means that the refill is broken inside, or it may be that something else is blocked. It is also possible that when inserting the pen, it is inserted too tightly, and the refill is too inside, which will also lead to idling.

How to deal with the idling of the pencil turner:

1. It is recommended to use a hard object to make the cone of the pencil a little hairy, and increase the friction to make the starting force, so that it does not slip. Remove the pencil sharpener swing hand. There must be a broken refill stuck in the knife inside, and it will be over when you pick it out.

2. If the pencil sharpener is not sharpened, it may be that it has been used for a long time, or the pencil lead has been broken in it before. It could also be that something is stuck on the turning blade. Pull it out with a needle, open it and clean it up.

The quality problem of the pencil I bought is that the lead core itself is relatively brittle. It may have been fallen, that is, after falling on the ground and shaking, it cannot be seen on the surface, but in fact, it is cracked inside.

Pencil sharpener. When using a pencil sharpener to sharpen a pencil, the technique must be gentle, gently turning round and round, and not in a hurry. After turning, when taking it out, be sure to gently "pull" it out straight and parallel to the round mouth of the pencil turner.

Note: Do not lift the tip of the pen into the knife when pulling it out, because the tip of the nose is already very small at this time, and it is indeed easy to insert it between the knife edges. ）

Pencil sharpener, a manual double-hole multi-knife pencil sharpener, comprises a pencil sharpener body knife, a knife body, a knife holder, four pencil sharpening core knives, a transparent upper cover, a conical cylindrical hole of a pencil sharpening core, a chip removal groove, a knife holder positioning type trace groove, and a feed positioning surface, wherein the pencil sharpening body knife is fixedly mounted on the cutter body, and four pencil sharpening core knives are fixed in the knife holder.

Pencil sharpener. The tool holder is fixed in the tool holder positioning groove, and then the transparent upper cover is fixed on the tool body, and the tool holder is pressed tight. The utility model discloses an advantage in that the step-by-step rolling effect of pen body and lead core is good, and the lead core is stressed evenly, and it is not easy to break, and the cutting length of lead core is easy to control, and the radial position of pencil in the rolling process is stable.

The multi-function pencil sharpener can be adjusted in five gears, and the length and thickness of the refill can be adjusted by rotating the adjuster, if the refill is cut off and stuck on the knife holder, the refill can be ejected by pressing the button (push), saving time and effort.

The safest and most convenient way to sharpen a pencil is with a pencil sharpener.

First, take a pencil that needs to be sharpened, put the end that needs to be sharpened into the hole of the pencil sharpener, then fix one pencil sharpener or pencil, and rotate the other. For example, the pencil sharpener does not move, and the pencil is turned. The pencil does not move, and the pencil sharpener is turned.

Then you will find that the sawdust is cut out of the blade, and when it is obvious that there are lead chips being cut out, it means that you have cut the lead of the pencil, if you like to use a finer pencil, you can sharpen it harder, and the thick pencil does not need to be sharpened too hard.

There is also the most primitive is to sharpen with a knife, hold the knife in the right hand, hold the pencil in the left hand, push the back of the knife with the thumb of the left hand and force it, and control the direction of the knife and the knife with the right hand. Turn some pencils every time you sharpen them, and then continue to sharpen them a second time after one turn, depending on your strength and the length of the nib you need. This method is dangerous due to the leakage of the blade, so it is not suitable for beginners in elementary school.

Sharpen the sketch pencil:

1. Take out an ordinary pencil sharpener and make it at a 60-degree angle to the pencil.

2. Cut the wood evenly and forcefully, and turn the pencil after a knife.

4. Use a knife to cut the pencil pencil, and the square-headed pencil needs to be sharpened on four sides.

5. The sharpening method of the pointed pencil is the same as that of the square head, carefully and evenly cut on each side until it is rounded.

The operational definition of sketching is the artistic activity of using a single color to express the change of brightness, painting tools, and deliberately shaping the form of an object in accordance with certain drawing principles on the picture carrier. Sketching is a variation of sketching. The level of sketching is one of the important indicators that reflect the painter's spatial modeling ability.

There are two possibilities, one is that the refill is broken before it is used, and the other is that the end of the refill is broken due to excessive force when sharpening the pencil sharpener.

Pencil sharpeners can be divided into ordinary pencil sharpeners and electric pencil sharpeners, ordinary pencil sharpeners are generally composed of three parts: the blade, the scabbard and the waste box.

Sometimes, you drop a pencil and the core inside it breaks. Look at the dots when you sharpen, not too long, not too short. It just feels right.

In fact, it is not the problem of the knife at all, it is the fault of the pen. Do you take a closer look at how many of the pencils at hand are positive? Are the two pieces of wood wrapped in the refill soft and the other hard? Therefore, even the cheapest pencil sharpener will not break the lead when it meets a qualified pen.

Well, the handle of your pencil sharpener can be twisted open, and it's possible that the broken refill of the pencil you broke last time is still stuck in it. Or it's your pencil sharpener blade that's too inward.,You use something to top out.,Be careful.,It's really not good.,I'll give you one.。。 Adopt me!

。。Change a pencil, I personally still like to use a knife, little by little slowly sharpened, ruthless and exquisite, I said buddy, let's use the automatic one!

The refill of the pencil is made of a material called graphite, but graphite is a very soft material, so it is easy to break it with a pencil sharpener, and there are many types of pencils such as 2B and HB
